Special Issue Information

Dear Colleagues,

Chromatography remains a cornerstone of pharmaceutical analysis, with recent advancements greatly enhancing its applications across diverse areas such as drug analysis, bioanalysis/pharmacokinetics, natural products, metabolomics, formulations, and nanotechnology. These innovations have improved efficiency, sensitivity, and sustainability while expanding the field’s scope.

This Special Issue aims to highlight recent progress and emerging trends in chromatography, focusing on techniques such as HPLC, UHPLC, GC, HPTLC, and SFC, coupled with various detectors. We welcome contributions exploring the following topics:

  • The drug analysis of chemical drugs and their formulations.
  • The analysis of biological drugs.
  • Bioanalytical applications in biological media, including pharmacokinetics, toxicology, metabolomics, proteomics, and anti-doping studies.
  • Advances in stationary phases for pharmaceutical applications.
  • Natural product research and applications.
  • Eco-friendly and sustainable approaches in pharmaceutical analysis.
  • The integration of experimental design and artificial intelligence (AI).
  • Miniaturization and microfluidic chromatography.

We encourage all researchers to submit original research and review articles that provide significant updates on the utilization of chromatography in pharmaceutical analysis.

We look forward to receiving your contributions and advancing the field together through this Special Issue.

Edaravone is used to treat motor neurone disease (MND) by slowing disease progression and prolonging survival time. Currently, it is available as an IV infusion (Radicava®, Jersey City, NJ, USA) and an oral liquid suspension (Radicava ORS®, Jersey City, NJ, USA). Development of novel edaravone formulations is still an active field of research that requires a validated stability-indicating assay capable of providing specific, precise, and accurate quantification of edaravone content. In this study, we developed and validated a stability-indicating reversed-phase high-performance liquid chromatography (RP-HPLC) method for edaravone quantification. Ten RP-HPLC methods based on the previously published literature were evaluated during method development. The optimal method employed a gradient method on an Agilent ZORBAX Extend-C18 column (150 × 4.6 mm, 5 µm) and produced a sharp and symmetrical drug peak. The method was further validated according to ICH Q2(R2) guidelines for specificity, linearity, sensitivity, accuracy, and precision. Successful separation of edaravone from void signals and degradant products was achieved. The method was precise and accurate at the concentration range of 6.8–68.6 µg/mL and was recommended to use without methyl hydroxybenzoate (MHB) as an internal standard. Full article

The sterility of ophthalmic drugs is a fundamental requirement for ensuring patient safety, and as such, it is subject to stringent regulatory standards. However, significant gaps remain regarding the effect of sterilization techniques on the impurity profile and relative content of active pharmaceutical ingredients (API). Previous research involving a set of five APIs used in ophthalmic preparations (dexamethasone, methylprednisolone, aciclovir, tetracycline hydrochloride, and triamcinolone) demonstrated that gamma irradiation led to the formation of specific impurities in the corticosteroids, dexamethasone and methylprednisolone. This study aims to further explore the effect of both gamma and electron beam (E-beam) irradiation on the impurity profiles of these APIs under varying conditions, with and without dry ice. The analyses were conducted using high-performance liquid chromatography with ultraviolet/visible light (UV/VIS) detection and the effect of sterilization conditions was assessed in accordance with the assay and related substances test outlined in the European Pharmacopoeia (Ph. Eur.). Additionally, this study investigated whether exposure in a controlled atmosphere with reduced oxygen or water content could mitigate the formation of impurities and influence the stability of the compounds. The results indicated a protective effect of low-temperature and low-oxygen environments during both gamma and E-beam irradiation but no effect of dry conditions. Full article
